Wow, that was awesome! You keep raising the bar, and you're getting better and better at it. The use of props have done well to enhance it. Thanks for making this!
As a suggestion to improve further, I think utilizing the camera in inventive ways could be a great thing to utilize.
If the software you are using allows you to create two cameras, you can record the scenes with each camera, one being up-close and one being at the normal position. Then you can show some events, and then replay it using the second camera.
But if there can be no second camera, I think utilizing some close-up shots to the heroine at the right times could improve it. For example, a camera placed beneath her and looking up as she is struck. A close-up to her face to show emotion and give her dialogue amidst the torture, like if she actually does beg for mercy.
Great job =)
